ABSTRACT:
The combination of a converter in which liquid petroleum gas is changed in phase from liquid to gas preparatory to fueling an internal combustion engine by adding heat from a fluid, a dual three-way valve, an air-fluid heat exchanger in a human-occupied compartment (the cab), and a fluid circulation system independent of the internal combustion engine cooling system. The dual three-way valve's position either directs engine coolant tapped from the engine through the converter and air-fluid heat exchanger, partially cooling the cab, or directs fluid from the independent fluid circulation system through the converter and air-fluid heat exchanger, fully cooling the cab. As an alternate embodiment for installations when engine coolant can become temporarily too hot to exit the inverter below ambient cab temperature, an independent bypass may be incorporated.
